3M 7010349783 Mastic Tape Compound 1.5 X 30 Ft

Product Description

The 3M 7010349783 is a self-fusing, conformable mastic tape compound from the Scotch-Seal 2229 series. It is used to seal, insulate, and protect electrical splices, cable jackets, and connections from moisture, corrosion, and environmental exposure. The tape conforms easily to irregular shapes and voids without adhesive, bonding to itself under hand pressure. At 1.5 inches wide and 30 feet per roll, it delivers substantial coverage per unit. Licensed electricians, low-voltage technicians, and cable splicing crews are the primary installers of this product.

This mastic tape compound is suited for use in residential, commercial, and industrial electrical applications. It is commonly applied over wire splices, conduit entries, underground cable terminations, and similar transition points where a conformable moisture barrier is needed. The Scotch-Seal 2229 series is widely used in direct-burial and above-grade electrical sealing work where a pliable, void-filling compound tape is required rather than a rigid or heat-shrink solution.

Key Features

• Self-fusing mastic construction conforms to irregular surfaces and void fills without tools
• 1.5-inch width provides versatile coverage for standard splice and cable jacket applications
• 30-foot roll length delivers extended run coverage per unit
• Bonds to itself under hand pressure with no adhesive required
• Provides a moisture and corrosion barrier at electrical connections and cable terminations

Compatibility

Designed as an OEM-style replacement and standard-use mastic compound tape for electrical splice sealing, cable jacket repair, and conduit entry sealing in residential and commercial wiring applications.

Installation Notes

Installation should be performed by a licensed electrician or qualified low-voltage technician following applicable NEC guidelines. De-energize all circuits before applying tape to splices or terminations. Stretch and overlap the mastic tape evenly around the splice area, ensuring full void fill and surface conformance. Avoid contaminating the mastic surface with oils or debris prior to application, as this can reduce the integrity of the seal.
